    Study Notes

    Linux Operating System

    • A repository is a collection of software for a Linux distribution on a server.
    • The package manager updates the operating system and other software periodically.
    • Linux is flexible and easily customizable, allowing users to change the desktop, menu position, status bar position, style, and more.
    • Linux has excellent support, with thousands of forums and millions of people ready to help open source software users.

    Advantages of Linux

    • Linux is free from viruses, eliminating the need for anti-virus software and reducing the risk of data loss.
    • Linux makes it easy to keep software up-to-date, preventing data redundancy and ensuring single copies of files.

    Database Management System (DBMS)

    • A database is a collection of organized data that can be shared among users with authorized access.
    • DBMS provides data privacy, allowing only authorized users to access data according to privacy constraints.
    • DBMS automatically takes care of backup and recovery, ensuring data is restored after a crash or system failure.
    • DBMS reduces application development and maintenance time.

    Primary Memory Storage

    • No specific information provided about primary memory storage.

    Linux vs Windows

    • Linux is different from Windows, but no specific differences are mentioned.

    Network Protocols

    • LAN (Local Area Network) is a network that connects devices in a limited geographical area.
    • MAN (Metropolitan Area Network) is a network that connects devices in a larger geographical area, such as a city or town.
    • WAN (Wide Area Network) is a network that connects devices over a wide geographical area, such as a country or continent.

    Introduction to DBMS

    • A database is a collection of organized data that can be used to make informed decisions.
    • Data is raw facts, while information is processed data that helps in decision-making.
    • Examples of databases include phone diaries, medical records, and student records.
    • DBMS provides an organized way to store and retrieve data.
